Chemical kinetics based solid propellant combustion predictive capabilities have developed to the point where it is possible to compute combustion properties of solid propellants. Specifically, burning rates over a range of pressures and temperatures.This capability will reduce the time, effort, and cost in developing solid propellants for a variety of combustion devices from rockets to air bags.BENEFITS: The ability to predict solid propellant combustion properties will reduce cost and effort indesigning and formulating new propellants. The cost savings to industry and the government are potentially enormous since only likely propellant formulations will be progress to the mix, cure, and testing phase of the development cycle.
